The Series RHPLC Wall Mount Humidity/Temperature Transmitter is a compact economical sensor for the building automation marketspace. The stylish housing is well vented to provide air flow across the sensor to improve measurement accuracy. Each unit utilizes a capacitive polymer sensing element to deliver a proportional analog output. A combination humidity and temperature model can be configured with current, voltage, RTD, or thermistor output. A wide selection of passive RTD or thermistor sensors are available in this series. • 2% or 3% accuracy models • Humidity only or temperature and humidity combo • Wide selection of passive thermistor or RTD temperature sensors • Air economizers • Room comfort monitoring FEATURES/BENEFITS SPECIFICATIONS DESCRIPTIONAPPLICATIONS SERIES RHPLC | WALL MOUNT HUMIDITY/TEMPERATURE TRANSMITTER ® SensorCapacitive polymer.
